The amount of oxygen in the flask through the intake tube illustrates proportions
The flask 99.35% will contain of oxygen after 5L have passed through the intake tube
How to calculate the percentage of oxygen?
To do this, we make use of the following representations
P for the proportion of oxygenV for te volume of oxygenx for the proportion of oxygen in the flask after 5 L passed throughSo. we have the following derivative
dP = dV - P * dV
Divide through by dV
dP/dV = 1 - P
Next, we set up the integral
[tex]\int\limits^x_{0.040} \frac {1}{1 - P}dP= \int\limits^5_0 {dV}[/tex]
Integrate both sides
[tex]-\ln(|P - 1|)|\limits^x_{0.04} = 5[/tex]
Expand
-ln(|x - 1|) + ln(|0.04 - 1|) = 5
Evaluate the difference
-ln(|x - 1|) + ln(|-0.96|) = 5
Express as a fraction
ln(0.96/|x - 1|) = 5
Express both sides as exponents with a base of 2
e^ln(0.96/|x - 1|) = e^5
Solve for x
x = 1 - 0.96/e^5
Evaluate the difference
x = 0.9935
Express as percentage
x = 99.35%
Hence, the flask 99.35% will contain of oxygen after 5L have passed through the intake tube

Sara and her friends are enjoying a bag of candy-coated chocolates. Just for fun, they remove 80 pieces of candy from the bag to check their color. The outcomes are shown in the table.
Candy Color Number of Candies
brown or orange 25
green or yellow 28
red or blue 27
Which statement is true based on the results in the table?
A.
All of the outcomes are equally likely because their relative frequencies are similar.
B.
All of the outcomes are equally likely because the relative frequency of picking brown or orange candies is greater than that of picking green or yellow.
C.
All of the outcomes are not equally likely because there is a lot of variation in their relative frequencies.
D.
All of the outcomes are not equally likely because the relative frequency of picking green or yellow candies is the highest.
E.
All of the outcomes are not equally likely because the relative frequency of picking red or blue candies is less than that of picking green or yellow.
Answer:
A
Step-by-step explanation:
There doesn't appear to be any particular color that has several more than the other choices.
Answer:
Option E
Step-by-step explanation:
If she picked them randomly than the 80 she picked are a pretty good representation of the candies in the bag, we know that there are different amounts of each candy based on Sara's numbers. According to her results, there are more green or yellow candies than brown or orange so the odds are there are more green or yellow candies in the bag. Since there are different numbers of each candy, the odds of her picking a certain color is different than the others, so the outcomes are not equally likely. The answeres can now be C,D, or E. I think it's option E because to me it seems like the most accurate of the three.

What is the dividend yield on Stock A that sells at
$15/share, when Company A pays a quarterly
dividend of $0.20 per share?
dividend yield = [?] %
Give your answer as a percent rounded to the
nearest tenth
Hint: Dividend Yield
annual dividend
share price
Answer:
5.3%
Step-by-step explanation:
The annual dividend is 4 times the quarterly dividend, so is $0.80 per share. The yield is the ratio of that to the share price:
yield = $0.80/$15.00 ≈ 0.05333... ≈ 5.3%
The dividend yield is 5.3%.
Write these numbers in order of size. Start with the smallest number. 3007 4435 399 4011 3333
Hey there!
Let's write all these numbers in order.
First, all numbers here are 4-digit numbers, except 1 (it's a 3-digit number)
So the smallest number is the 3-digit number.
399
Now, what's next?
let's check the thousands place (the first digit in the 4-digit numbers)
We see 3, 3, 4 and 4.
3 is smaller than 4.
Now we have 2 numbers: 3007 and 3333.
Well, which one's smaller? that's right, 3007.
So we have
399, 3007.
The third number is 3333 (the thousands place is 3)
so we have
399, 3007, 3333
Now, we have 2 numbers left, and they have a 4 in their thousands place.
The numbers are: 4011 and 4435.
Well, which one's smaller? that's right, 4011, and the greatest number is 4435.
Hence, we have

Answer:
a. y = 7.5x + 1
b. y intercept is 1, which means the puppy weighed 1 pound at birth or at 0 months old.
c. slope is 7.5 which means puppy gained 7.5 pounds a month for the first 6 months.
Step-by-step explanation:
To find slope: use rise/run formula (y2 - y1 / x2 - x1) which is,
(23.5 - 16) / (3 - 2) = 7.5
To find y intercept: Plug in y, x and b in the slope intercept formula (y=mx+b). choose any one of the pairs from the table. i chose 2 and 16. plug it in and the formula would now look like 16 = 7.5(2) + b .
solve for b
16 = 15 + b (multiply 7.5 and 2)
1 = b (subtract 15 from 16)
y intercept is 1

For a period of time, an island’s population grows at a rate proportional to its population. If the growth rate is 4.5% per year and the current population is 1500, what will the population be 6 years from now
The population of the island with growth rate of 4.5% per year and the current population is 1500 is 1953 after 6 years.
How to solve an exponential function
Let y represent the population after x years.
Given that the growth rate is 4.5% per year and the current population is 1500.
Hence a = 1500, b = 100% + 4.5% = 104.5% = 1.045
y = 1500(1.045)ˣ
After 6 years:
y = 1500(1.045)⁶ = 1953
The population of the island with growth rate of 4.5% per year and the current population is 1500 is 1953 after 6 years.

inches from the vertex of the pyramid. If the height of the pyramid is Sinches, what is the area of the rectangular base?
The rectangular base area is the space the rectangular base occupies
The area of the rectangular base is 60 square inches
How to determine the area of the rectangular base?The diagram is not given. So, I will apply provide a general solution.
Using the similar shapes concept, the area of the rectangular base can be represented as:
Ratio = Height : Area
This gives
3 : 36 = 5 : Area
Express as fraction
36/3 = Area/5
Evaluate the quotient
12 = Area/5
Multiply both sides by 5
Area = 60

Which method do you prefer when comparing numbers written in scientific notation? Explain why you prefer this method using examples. PLS HURRY
Answer:
If two numbers have the same exponent for 10, then compare the decimal numbers to determine the greater number. Sometimes you may have to compare two numbers, but only one of them is in scientific notation. In that case, convert the number that is not in scientific notation into scientific notation first. Then, compare the two numbers. Example 1 : Compare 5.62 x 10 6 and 7.39 x 10 5.
Step-by-step explanation:
The general form in scientific notation is
z.z ×10^zwhere z is integer
So while comaparing
We usually compare z.z rounded to similar significant numbers .
In rest case
we use power of 10 ,the number which has higher that's bigger.Example
